Suspension Hook

ABSTRACT

The present invention encompasses an arrangement ( 1 ) related to a suspension hook with a discrete anchorage portion fixable via fixing means ( 3 ,( 3 )), to a vertically orientable support ( 2 ) and a discrete hook portion ( 5 ) coordinated with the anchorage portion. Said anchorage portion ( 4 ) displays an elongate surface section ( 4   a ) with barbs ( 6 ), while said hook portion ( 5 ) displays a short surface section ( 5   a ) with corresponding barbs ( 7,8 ) in order, in a position with the barbs cooperating, to cause the retention of said hook portion ( 5 ) against the anchorage portion ( 4 ) in one set position selectable from among a plurality of such positions. A vertically directed loading (‘F’) acting on the hook portion ( 5 ) is adapted to be absorbed by a cooperation between said barbs ( 8 ) allocated to the hook portion and barbs ( 6 ) allocated to the anchorage portion. Said surface section ( 5   a ) associated with the hook portion displays two series-oriented surface sections, a first surface section ( 8 ) structured with said barbs ( 7 ) and a superjacent, adjacent second surface section ( 9 ) which is structured planar. Said barbs ( 8 ) are disposed to be oriented adjacent and laterally oriented in relation to a lower plane (‘P’) allocated to the lower surface of the second surface section ( 9 ).

TECHNICAL FIELD

The present invention relates in general to an arrangement which isdirectly related to a suspension hook, and more specifically to asuspension hook which is adapted for cooperation with a verticallyorientable support, and which displays a, hereinafter referred as“anchorage portion” fixable to the support and adapted, via discretefixing means, to be fixable against said support and a “hook portion” orcatch portion coordinated with the anchorage portion and formed as adiscrete unit.

More particularly, the suspension hook is intended to utilise ananchorage portion which displays a vertically directed elongate surfaceportion with a first set of barbs or other unevenness, and a hookportion which displays a surface section with a corresponding second setof barbs in order, in a position of cooperation of the sets of barbs, toretain said hook portion against the anchorage portion in a position setfrom among a plurality of optional positions and where a verticallydirected load acting on the hook portion is adapted to be absorbed bysaid barbs allocated to said anchorage portion and said barbs allocatedto said hook portion.

More particularly, the present invention relates to an arrangement in asuspension hook, where the hook portion, in a selected position, mayassume a fixed and retainable cooperation with the anchorage portion,where this retainable cooperation may advantageously increase independence upon the size of the load disposed at the hook portion, andwhere the hook portion may in a simple manner be displaced to avertically related position selected from among a plurality of optionalpositions.

The fixed cooperation is based on the feature that the first set ofbarbs allocated to the anchorage portion is, in fixed cooperation withthe second set of barbs allocated to the hook portion while theintimated vertically related displacement is to be able to take placewithout such fixed cooperation.

DESCRIPTION OF CURRENTLY PROPOSED EMBODIMENT

By way of introduction, it should be emphasised that, in the followingdescription of two currently preferred embodiments which display thesignificative characterising features associated with the presentinvention and which are clarified by means of the accompanying Drawings,we have selected terms and a special terminology with the intention insuch instance principally of clarifying the inventive concept as hereindisclosed.

However, it should be observed in this context that the expressionsselected here should not be seen as restrictive exclusively to the termsutilised here and selected but it should be understood that each suchterm is to be interpreted so that, in addition, it encompasses alltechnical equivalents which function in the same or substantially thesame manner in order in such instance to be able to attain the same orsubstantially the same intention and/or technical effect.

With reference to accompanying FIGS. 1 to 7, the Drawings schematicallyand in detail show the basic preconditions for the present invention ina first embodiment and where the significative properties associatedwith the present invention have been given concrete form as a result ofthe now proposed and hereinbelow more closely described firstembodiment.

Thus, FIG. 1 illustrates an arrangement 1, relating to a suspension hookwith a discrete anchorage portion 4 fixable via fixing means 3 (3) to avertically orientable support 2 and with a discrete hook portion orcatch portion 5 coordinated with the anchorage portion 4.

Said anchorage portion 4 displays an elongate surface section 4 a withseries-oriented barbs 6, and said hook portion 5 displays a surfacesection 5 a with corresponding barbs 7.

More particularly, this is a matter of the feature that said anchorageportion 4 is to display an elongate, vertically directed surface section4 a with a first set of barbs 6, and that said hook portion 5 is todisplay a short vertically directed surface section 5 a with a secondset of corresponding barbs 7, where the barbs 6 and 7 correspond to oneanother.

In a position of cooperation for the barbs 6, 7 (see FIG. 5), thesefixedly retained said hook portion 5 against the anchorage portion 4where a loading “F” is adapted to be absorbed by a clamping cooperationbetween said barbs 7 associated with the hook portion and said barbs 6associated with the anchorage portion.

More particularly, it is illustrated that said barbs 7 associated withthe hook portion are related to the surface section 5 a associated withthe hook portion which displays two series-oriented surface sections 8,9, a first surface section 8, structured with said barbs 7 associatedwith the hook portion and an adjacent second surface section 9structured slidably over the barbs 6, for example planar, and that saidbarbs 7 are to be disposed and be oriented adjacent and laterallyoriented a lower plane “P” allocated to the lower plane of the secondsurface section 9.

It is further disclosed that said surface section 5 a associated withthe hook portion is to be adapted, with said first surface section 8, tomerge into an integrated short planar surface section 9 but neverthelessslightly longer than said surface section 8 and where the planar surfacesection 9 is oriented to terminate adjacent a spiculated hook portion orend portion 5 b allocated to the hook portion 5.

A rotation, caused by an activating compressive force “F1” (see FIG. 4)of the hook portion 5 about an allocated axis of rotation 5 c against aresilient resistance generated by the anchorage of the tongue-likeportion 9 in the hook portion 5 is adaptable for lifting and releasingthe barbed surface section 8 of the hook portion 5 from the barbed 6elongate surface portion 4 a of the anchorage portion and thereby offera simple displacement of the discrete hook portion 5 along the anchorageportion 4 from a first selected position of adjustment to anotherselected position (according to FIG. 1).

Said hook portion 5 displays an elongate recess 10 or a cavity adaptedfor free cooperation with a rail 11 associated with the anchorageportion and where said cooperation makes for a stop of a rotationaltendency of the hook portion 5 under a loading “F”.

Said cooperation is adapted to form an abutment for said hook portion 5in a position of cooperation of the barbs 6, 7, according to FIG. 5.

More specifically, it is disclosed that said rail 11 is formed with athin or narrow portion 12 facing towards the anchorage portion 4 and abroad portion 13 facing away from the anchorage portion 4 for forming a“T” in cross section.

It is hereby disclosed that the barbs 6, 6 a may be oriented on eitherside of a narrow portion 12 of the rail 11 and are given a widthcorresponding approximately to twice the width of said narrow portion12.

An end portion 5 b is adapted to extend towards and ideally somewhatpast an end termination 9 a associated with the planar surface section 9and with a distance “d1”.

It is more particularly disclosed that said planar surface section 9 isto be disposed to extend towards and an adaptive distance past saidangle of rotation 5 c, where this distance is designated “d2”.

The relationship between the total longitudinal extent of the planarsurface section 9 and the barbed surface section 8 is selected to be aratio which is greater than 1:1 and respectively to less than 2:1.

Said hook portion 5 displays a substantially parallelepipedic basic formor basic body 5 d with a hook unit 5 e integral with the basic body 5 das a narrow superjacent section whose end portion 5 b is adapted toextend towards and an adapted short distance past a portion 5 fterminating the basic body after said end termination.

More particularly, the invention discloses that said barbed firstsurface section 8 is to be adapted to extend over said planar secondsurface section 9 a distance “d3” corresponding to or slightly exceedinga depth allocated to the barbs 8.

Of importance to the illustrated embodiment is that the bending orrotation of the hook portion 5 about the axis of rotation 5 c will be ofsuch an extent that the cooperation between the barbs 8 and the barbs 6ceases.

It is more particularly disclosed to cause said loading “F” to beadapted to urge the barbs 8 associated with the hook portion towards thebarbs 6 associated with the anchorage portion by causing said barbs 8, 6to be structured as a saw tooth configuration, according to FIG. 6, withbearing surfaces 15 for the barbs 6 and bearing surfaces 16 for thebarbs 7 formed from a portion with a right angle (or slightly acuteangle) in relation to said plane “P”.

With reference to FIG. 1, it should particularly be observed that theanchorage portion 4 is given a slightly thinner form at its upper endportion and in association with the fixing means 3 than at its lower endportion and in association with the fixing means (3).

The thickness difference can in the normal case be selected to 2-5 mm,depending upon the length of the anchorage portion.

The holes for the fixing means 3 and (3) are advantageously directed atright angles to the surface 4 a and thereby give a slightly obliquepositioning downwards at the anchorage to a vertical “V” wall portion 31(2).

Said fixing means 3 (3) can depending upon the substrate of the wallportion 31 be selected as nails, screws, plaster board nails, concretepins and the like.

FIG. 6 is intended to illustrate the cross sectional configuration ofthe barbs which are associated to a saw tooth configuration where forceabsorbing surfaces 16 are at right angles in relation to force absorbingsurfaces 15 associated with the anchorage portion where these surfacesare oriented at right angles to the surface 4 a and which in that theanchorage portion 4 is tapering upwards will be inclined somewhatupwards from a horizontal plane.

This is illustrated with some exaggeration in FIG. 6.

It is particularly disclosed that the distance between adjacent barbsshould be selected to correspond to or slightly exceed 1.0 mm but shouldnot exceed 5.0 mm.

FIGS. 7 to 10 are intended to illustrate in different side elevations asecond embodiment of a hook portion.

This second embodiment is intended to clarify in cross section thesignificant coordination for the present invention between the anchorageportion and a new embodiment of the hook portion.

In FIG. 7 to 10, corresponding parts in the embodiment according to FIG.1 to 6 have been utilised.

The present invention is naturally not restricted to the embodimentdisclosed above by way of example but may undergo modifications withoutdeparting from the scope of the inventive concept as illustrated in theappended Claims.

In particular, it should be observed that each illustrated unit and/orcircuit may be combined with each other illustrated unit and/or circuitwithout departing from the scope of the appended Claims and the presentinvention in order to be able to attain the desired technical function.

The arrangement as claimed in claim 1, characterised in that a rotation, caused by the activating compressive force, of the hook portion about an allocated axis of rotation against a resilient counterforce generated by the anchorage of the thin tongue-like portion in the hook portion is adaptable to release the barbed surface section of the hook portion from the barbed elongate surface section of the anchorage portion and thereby offer a simple displacement of the hook portion along the anchorage portion from a first selected adjusted position to another selected position.
 6. An arrangement, relating to a suspension hook, with an anchorage portion fixable via fixing means to a vertically orientable support and a hook portion or catch portion coordinated with the anchorage portion, said anchorage portion displaying an elongate surface section with barbs, while said hook portion displays a short surface section with corresponding barbs in order, in a position with the barbs cooperating, to cause retention of said hook portion against the anchorage portion in one set position among a plurality of selectable positions, where a vertically directed force or loading acting on the hook portion is adapted to be absorbed by said barbs allocated to the hook portion and barbs allocated to the anchorage portion, that said surface section associated with the hook portion displays two series-oriented surface sections, a first surface section structured with said barbs and an adjacent second surface section which is slidably structured, such as planar, characterised in that said surface section associated with the hook portion is adapted, with said first surface section, to merge into an integral short planar surface section which is however somewhat longer than said first surface section where the end portion of the planar surface section is oriented adjacent a spiculated hook portion or end portion allocated to the hook portion, that said planar surface section is related to a thin tongue-like portion and is thereby resilient on an activating compressive force against the spiculated end portion of the hook portion, that said barbed first surface section is adapted to extend over said planar second surface section a distance corresponding to or slightly exceeding a depth allocated to the barbs, and that a rotation, caused by the activating compressive force, of the hook portion about an allocated axis of rotation against a resilient counterforce generated by the anchorage of the thin tongue-like portion in the hook portion is adaptable to release the barbed surface section of the hook portion from the barbed elongate surface section of the anchorage portion and thereby offer a simple displacement of the hook portion along the anchorage portion from a first selected adjusted position to another selected position.
 7. The arrangement as claimed in claim 1, characterised in that said hook portion displays an elongate recess or a cavity adapted for free cooperation with a rail associated with the anchorage portion and where said cooperation makes for a stop of said rotation of the hook portion under loading.
 8. The arrangement as claimed in claim 1, characterised in that said cooperation is adapted to form an abutment for said hook portion in a position where the barbs are cooperating.
 9. The arrangement as claimed in claim 1, characterised in that said rail is formed with a thin or narrow portion facing towards the anchorage portion and a wide portion facing away the anchorage portion for the formation of a cross section formed as a “T”.
 10. The arrangement as claimed in claim 6, characterised in that barbs oriented on each side of the narrow portion of the rail are given a width corresponding to twice the width of said narrow portion.
 11. The arrangement as claimed in claim 1, characterised in that an end portion is adapted to extend towards and ideally somewhat past the end termination associated with the planar surface section.
 12. The arrangement as claimed in claim 1, characterised in that said tongue-like portion is adapted to extend past a centre line allocated to the hook portion.
 13. The arrangement as claimed in claim 1, characterised in that said planar surface section is disposed to extend towards and an adapted distance past said axis of rotation.
 14. The arrangement as claimed in claim 1, characterised in that the ratio between the longitudinal extent of the planar surface section and the barbed surface section is selected to be a ratio of greater than 1:1.
 15. The arrangement as claimed in claim 1, characterised in that the ratio is selected to be less than 2:1.
 16. The arrangement as claimed in claim 1, characterised in that said hook portion displays a substantially parallelepipedic basic form or basic body with a hook unit integrated with the basic body as a narrow section whose end portion is adapted to extend towards and an adapted short distance past a portion terminating the basic body.
 17. The arrangement as claimed in claim 1, characterised in that said barbed first surface section is adapted to extend over said planar second surface section a distance corresponding to or slightly exceeding a depth allocated to the barbs.
 18. The arrangement as claimed in claim 1, characterised in that said loading is adapted to urge barbs associated with the hook portion towards barbs associated with the anchorage portion.
 19. The arrangement as claimed in claim 1, characterised in that said barbs are structured as a saw tooth form with a bearing surface formed from a portion with a selected angle to said plane.
 20. The arrangement as claimed in claim 1, characterised in that the anchorage portion tapers upwardly with a first surface and a second and inclining surface facing towards the support.
 21. The arrangement as claimed in claim 1, characterised in that holes allocated to the fixing means in said anchorage portion are obliquely oriented, such as at right angles to said inclining surface.
 22. The arrangement as claimed in claim 20, characterised in that the tapering is selected to be 2 to 5 mm.
 23. The arrangement as claimed in claim 1, characterised in that said barbs associated with the anchorage portion and hook portion display planar bearing surfaces oriented at right angles to said inclining surface.
